Python 3.9.2 (tags/v3.9.2:1a79785, Feb 19 2021, 13:44:55) [MSC v.1928 64 bit (AMD64)] on win32
datetime.fromtimestamp() fails for naive-datetime values prior to the start of the epoch, but for some reason works properly for aware-datetime values prior to the start of the epoch.
This is at least inconsistent, but seems like a bug.
Negative timestamps for dates prior to the start of the epoch are used by yahoo finance and in the yfinance module.
>>> import datetime
>>> start = int(datetime.datetime(1962, 1, 31, tzinfo=datetime.timezone.utc).timestamp())
>>> start
-249868800
>>> start = int(datetime.datetime(1962, 1, 31).timestamp())
Traceback (most recent call last):
File "<pyshell#3>", line 1, in <module>
start = int(datetime.datetime(1962, 1, 31).timestamp())
